Enterprise Systems Development
- 1. ISD ERP ESD
- 2. Technically internal specialized external Different background rewards discuss No direct Team customer contact groups Direct customer consensus contact What we do….. How we do…..
- 3. Separation from the user (no users involved) User’s concerns filtered by intermediaries Product-oriented view Entrepreneurial Process called for user involvement at key stages Use of joint-application design(JAD) techniques Extensive interim documentation Bureaucratic
- 4. • Experimental and Evolutionary Prototyping – Prototype presented by developers vs. expectations of the end customer testing group • Agile Systems Development – High degree of creative conflict possible due to strong customer involvement e.g. DSDM • Computer-Aided Software Engineering (CASE) – Because of mostly automated process there is less room for creative conflict • Component Based Development (CBD) – Some potential for creative conflict because components have to fit to the overall goal But: Standardized components can be used and are predictable from the start
- 6. package software employees are set up as a team but usually work independently. Custom software employees are usually individual workers but in fact they often work as a team. Reasons for the paradox: For package software time and goal are predefined. Because of that package software developers don’t have to align all the time and try to achieve the overall goal on time. Custom software employees got individual ideas and goals. To achieve a stable and usable product they have to align to create a common product with individual features.
- 9. Trend in recent years ….. …. open source software Specialized C o m p a n y General package custom S o f t w a r e
- 10. Qualitative Research Critic: Small group of observed companies treated as general business environment The ration of the research period was not distributed. No equal research period Generalizing assumptions that can’t be drawn upon this research (e.g. all package software companies employ PHD holders)
